摘要： Methods and systems for improving vacuum generation for an engine that may be operated at higher altitudes are presented. In one non-limiting example, a transmission that is mechanically coupled to the engine may be shifted from a gear to neutral in response to an actual total number of times a vehicle brake pedal is applied and partially released while the vehicle is stopped and the brake pedal is applied.

摘要： A pulley for a continuously variable transmission (CVT) and a method of controlling the pulley. The pulley has a main shaft, a fixed sheave, a mobile sheave and a cam system. The fixed sheave is fixedly mounted on the main shaft and has a fixed belt groove portion. The mobile sheave is movably mounted on the main shaft and has a mobile belt groove portion, the mobile sheave is mounted on the main shaft such that the fixed belt groove portion and the mobile belt groove portion form a riding path for a drive belt and is axially movable with respect to the main shaft such as to vary an effective diameter of the pulley by increasing or decreasing an axial space between the mobile sheave and the fixed sheave. The cam system is mounted at one end via a bearing fitted around the primary shaft to the mobile sheave. The cam system is adapted to provide an axial movement to the mobile sheave in order to increase or decrease the axial space between the mobile sheave and the fixed sheave.

摘要： An apparatus and method for a shift control of a vehicle are provided. The apparatus includes a road information obtaining unit that obtains road information of a road on which the vehicle is traveling and traffic information and a front vehicle detection unit that obtains front vehicle information including a speed of a front vehicle. A running state obtaining unit obtains an average running speed of the vehicle and determines whether the vehicle is traveling at a high constant speed based on the road information, the traffic information, and the average running speed. A shift controller adjusts a shift time of a transmission based on the front vehicle information when braking occurs during high constant speed traveling of the vehicle.

摘要： A control unit in a work vehicle executes an automatic downshift for shifting a speed range of a transmission to the speed range at a lower speed than a current speed range. The control unit determines the execution of the automatic downshift on the basis of automatic downshift conditions. The automatic downshift conditions include whether the operating amount of the accelerator operating member is equal to or greater than a predetermined accelerator threshold, whether the vehicle speed is less than a predetermined speed threshold, and whether the acceleration is equal to or less than a predetermined acceleration threshold.

摘要： The present invention relates to a launch control unit for selectively engaging a revised shift control strategy. The revised shift control strategy is operable to control an internal combustion engine and/or an automatic transmission of a motor vehicle. The launch control unit can be configured to receive a brake signal from a foot brake and a torque demand from a throttle pedal. In use, the launch control unit is operable to engage said revised shift control strategy upon receipt of a torque demand greater than or equal to an upper torque threshold within a predefined time period of receipt of a brake signal less than or equal to a lower brake threshold.

摘要： A transmission system for vehicle includes a clutch disposed in a power transmission path between an engine and a vehicle wheel, a transmission disposed in the power transmission path, a clutch actuator, a shift actuator, a vehicle wheel speed sensor, a sudden deceleration detecting unit that detects a sudden deceleration of the vehicle wheel based on an output signal of the vehicle wheel speed sensor, and a shift control unit. The shift control unit executes an ordinary shift control to shift to a speed adaptive shift stage associated with the rotational speed and to execute, when the sudden deceleration detecting unit detects the sudden deceleration of the vehicle wheel, a sudden deceleration adaptive shift control to shift to a shift stage lower than an actual shift stage at the point of detection of the sudden deceleration and higher than the speed adaptive shift stage associated with the rotational speed.
